Damn. Ok ill explain. Right out of the ship that you crash land in, go around the cornor and beat down the grunt. Then, jump on the door frame near the light. Crouch jump onto the roof. From thier, ull see a ledge from where you just came. Jump on that and walk until the boards barrier stops you. Face the shorter of the walls and throw a granade down and time the jump. IT sould get u on the wall which allows you to go through the wall. Then jump across and keep going. There is another part to the jumping, but i am to drunk to explain it right now. More coming later
